It's well known in esports that South Korea leads the world in League of Legends and certain other esports. By a long shot. How long? Compare it to the USA in international basketball, where the US has won 15 gold medals in 19 Olympics and silver or bronze in an additional three.
Team Liquid League of Legends coach Choi "Locodoco" Yoon-sub, himself from South Korea, says the esports infrastructure in his country of birth contributes to the concentration of talent there, much as the NBA fosters top-tier basketball teams and players in the USA.
Will "the gap" close anytime soon? Like the situation with Olympic basketball, the distance between the front-runner and everyone else may slowly start to close, but South Korea will be ahead of the pack for some time to come.
